Annotation:

Over the past years, biological activated carbon (BAC) technology has been successfully used for drinking water production and wastewater treatment. However, the present guidelines on the operation of BAC systems hardly exist, especially for BAC that are being employed to remove slowly biodegradable organics, e.g. pharmaceuticals and pesticides.
The first chapter of the dissertation comprises the effect of easy biodegradable organic compound acetate for the adsorption, desorption and biodegradation of slowly biodegradable pharmaceutical metoprolol. The effect of activated carbon surface roughness and suspension mixing intensity in the reactor for metoprolol removal efficiency and loaded activated carbon bioregeneration is being described extensively in the second chapter. The third chapter studies the effect of activated carbon characteristics for metoprolol adsorption–desorption hysteresis and how this affects the performance and bioregeneration of BAC reactor. The conclusions and recommendations were withdrawn based on the obtained results.
